Casing On the contrary to the arrangements habitually used in theconstruction of taximeters, the box of the hereinafter describedapparatus is constituted by a sheet-iron plate B0 having the shape of aninverted U riveted on a base Baa The box acts as a frame for themounting of the different mechanisms supported by rings or squaresriveted on the sides of the. U or on the base of the box. The closing ofthe box is obtained with two panels sliding into grooves R provided inthe U (Fig. 6).

The panel located on the side where the indications of the drums are tobe read is provided with a plate-glass covering a plate pierced withwindows through which appear the different indications of the tariffused the tare of the travel, the extras and the difierent integratingcharges.

Mounting of the flag The taximeter is provided with sets of easilydetachable mechanisms having between them only a few points of contact,the determination of which does not necessitate any adjustment. l

The shaft 1 (Figs. 2, 4 and 36) extends through all the apparatus andengages by tenons and mortises 1a a cam' 6 rotating in the ring 5riveted on one of the sides of the box B0. The other end of the shaft 1rotates in a tube 89 also riveted on the box B0. The cam 6 is providedwith notches or recesses in which the end of a lever 7 engages, whichlever is under the action of a powerful spring 8 (Fig. 8) and swings ona spindle 21 (Fig. 4) carried by the casing Bo. The object of thisarrangement is to determine accurately "H35 press dow-n again the flag.

At each of these positions, the pinion 41 is maintained in the correctposition by a spring 42 and a recess n on the plates 34, so that thereis always a short tooth of 41 which occupies the diametral positiondetermined by a line connecting the shaft 1 and the spindle of thepinion 41 (Figs. 23-24-40 and 41).

All these drums 45 to 49 or discs 57, 64, 65 carry different devices ormembers, the mounting, the function and the Working of which will behereinafter described.

Tarif drums On the projecting part of the shaft 1, out

ofthe tube 25, is located a drum 75 on the periphery of which are theindications given through the tariff window and stating the position ofworking occupied by the taximeter.

This drum 75 (Figs. 12 and 36) comprises a web 75a,l connecting itsouter part with a hub 75a. he drum 7 5 is in egral in rotation with theshaft 1 by means of a key 7 5. The drum is provided with a circular edgeformed as a cam at 7 7 acting on a. lever 105, pivoted in 106 (Fig. 12)and engaging and disengaging the time movement. By the cam surface 76dressed on the circular inner part of the drum 75, the latter acts on apin 103 of a lever 101 Which, pivoting about a spindle 102 mounted on aplate 94 (Fig. 12), applies a spring 104 to the balance wheel 100 of thetime movement which is of an usual known system. In this Way, it stopsthe balance Wheel 100 and restores it when the lever 101, returned bymeans of a spring 101 (Fig. 12), leaves the balance Wheel.

Winding up 0f the clock lwork spring On the drum (Fig. 12) is secured at82 a ratchet Wheel 82 which is in contact with a pawl 83 secured on thebarrel 86 loosely mounted on the tube 89. When the flag 2 isi'nanipulated in the normal direction of rotation, the barrel spring 88is Wound up.

For preventing the spring 88 from being overwound, the barrel 86 carriesa member 84 pivoted at- 84 on 86 and comprising a pin 85 traversing anaperture of the vert-ical Wall of the barrel 86. vThis pin 85 engagesbetween the two last spires of the spring 88 so that when, inconsequence of the winding up, the convolutions approach the shaft 1,the member 84 oscillates about its pivot 84 and rests on the tail of thepawl 83, thus liberating the i, ratchet Wheel 82.

The d rum 75 with the ratchet wheel 82 and the shaft 1 may then rotatewithout carryinaway the barrel 86.

he movement of the spring 88 is transmitted by means of a large pinion90 (Figs. 2, 7o 4, 6, 36) and by means of a number of intermediatepinions 91 to the escape mechanism mounted in a cage 98 (Fig. 6) andfastened on one of the plates 94 of the clockwork. The other plate 93 ofthis system bea against the casing Bo of the a paratus an the Whole isfixed in osition y means of struts 96 (Fig. 2) gui ed on pins 95 rivetedon the casing Bo, the whole being tightened up by nut-s 97. 30

A spindle 92a (Figs. 2, 6 and 7) of the 'i clockwork drives the pinion108 always in engagement with a pinion 113 integral with a slidingsleeve 114 integral itself with a ratchet Wheel 115 and transmitting itsmovef 5 ment by means of a pawl 117 integral with a hub 118 integralitself with the wheel 124. All these members are loosely mounted on thespindle 112 and the hub 118 is maintained in position by the ring 116keyed on 112 andlgso the Wheel 124 is always in engagement with thewheel 64 (Fig. 36).

Removable bearing of the worm The flexible drive 172 coming from the g5Wheel of the vehicle is integral with a member 173 driving, by tenon andmort-iso, a hollow spindle 166 rotatable in a ring 167 fixed on the baseBw of the casing Bo by means of screws 167. The spindle 166 is integralwith a pin 165 of the Worm 164, the upper end of which rotates in asquare bearing 163 (Figs. 2 and 4) fixed on its base on the ring 167, acorresponding hole being provided 1n the base Bw of the box Bo.

The Worm 164 drives the toothed Wheel 161 the number of teeth of whichis corresponding to the diameter of the tvre-wheel of the vehicle.

The wheel 161 is integral with the conical pinion 160, rotating aboutthe spindle 162 fixed on the bearing 163.

Besides the taXimeter can be actuated by a running Wheel of any suitablediameter; to this purpose, Without removing any internal number of thetaximeter nor any closing members of the casing, it is sucient todismount the screws 167, to withdraw the ring 167 secured to the worm164 and to the bearing 163, to unscrew the spindle 162 and to replacethe worm wheel 161 or the pinion 160 by another Wheel of a differentnumber of teeth, to change as required the worm 164 and to remount theseparts.

Fastening of the taan'mter 125 The taximeter is fixed to the vehicle insuch a manner to be oriented at will in the direction which allows tothe client to read the most easily the indication of the' dial. For 130this purpose (Fig. 4) the ring167-zis tight-y ened' up(` onthe support169, withy the interposition of a soft washer 168',`by meansjofaf speedymechanismwhich provides different" taritsfbr the drive (three in thiscase), Thismechanism is represented in Figs. 4 andr36 '2 for thepositionofi Tariff Bland inFig.'` 6'for the positionl of' Tariff" 1`,andcompvises the if'ollowi'ngl members. y p

This transmission device byf-means of'pin ions 41 with alternatelylongand short teeth is w'el-l'known but, in thistaximeterpthis device ischaracterized by the factthat in priniso with a pin 71 integral with thedisc 65.

-l of a 40 10 revolution. The drum 47, bearing 10 numerals and twograduations 15, 35, 55, 75, 95. carries two sectors 7L with 4 teeth op-47 a rotation corresponding to `posite each other and transmits, foreach halfrevolution, a rotation of 1-10 of revolution to the dollarsdrum 46.

The latter bears also 10 numerals 0 to 9 and transmits, at eachrevolution by means of a sector k provided with 2 teeth, a rotation ofbears 2O numerals (0 to 19).

All the drums 45, 46 and 47 and the disc 57, having not the same angularspace to travel, do not begin their rotation simultaneously, whichallows the use of a smaller spring 61 than necessary if all thesemembers would be driven simultaneously in rotation.

If the cents drum 47 would bear a double numbering, 00, 25, 50, 75 itwould be only provid-ed with 8 numerals and should be rotated throughl/g of revolution. In this case, the star 51 might be only provided with6 or 5 teeth and the rotary motion would-decrease from the disc 57(rotating through or 1g of revolution) to the drum 45 (rotating ofrevolution to the drum which through of revolution).

Extras mechanism The mechanism for registering the extras is alsocontrolled by the manipulation of the flag. It is arranged between thewheel 64 and the tariff drum 75 (Figs. 2, 4, 12, 16, 16 and 36).

This mechanism comprises a disc 65 loosely mounted onA the hub 34 of thelast left meinber 34 (Figs. 16n and 36) and two connecting drums, theone of which 49 is loosely mounted on the hub of a member 34, and theother 48 loosely mounted on the hub of the star wheel 51 (Fig. 36).

The drums 48, 49 and the members 34 are of the same construction thanthat a-lreadv described for the registering of the tare. i

The tariff drum (Figs. 12 and 16) carries on its flat surface 7 5X a pin7 2 engaging the hub` 75a ofthe drum 75, a ring 73 can rotate under theaction of a spring 7 4( Fig. 12) fixed, on the one hand, on the ring 73and, on the other hand, on 75. This ring constantly tends to apply thepin 7l against the pin 72.

The disc 65 carries a. pawl 66 and a curved lever 68. The pawl 66 isplaced under the action of a spring 67 and can oscillate in adiametrical plane of the disc 65; the lever 68 is placed under theaction of a spring 69 and can be displaced in the plane of the saiddisc.

When the flag is coming from the position Payment to the position Extras(Figs. 3, 1

16 and 16) the inclined edge of the pawl 66 meets the short tooth of thepinion 41 carried bv the sliding member 35 of the drum 49 and the pawl66, sliding on this tooth of the pinion 41. falls behind this tooth (seeFig. 16).

In order to indicate the extras, it is necessary then to move the flagin the opposite direction between the position Extras and the positionPavment. This retrograde motion of the flag is transmitted to the pinion41 by the shaft 1. the drum 75 and the pins 71, 7 2, the ring 73. thespring 74. the disc 65 and the pawl 66. In order that the extras shouldbe registered impulsively and not in a continuous manner, the followingmembers come into action.

Bv reason of the rotation of the shaft 1 in the direction stated by thearrow F1- (Figs. 10. 12. 16) the back of the pawl 66 (that is to sav thepart opposite to the inclined edge of the latter) engages with a shorttooth of ther pinion 41 and cannot rotate the latter becausev thefollowing long tooth of the said pinion does not find a correspondingaperture on the internal circular and fiat face 65' of a disc 65 (Fig.9). Consequently the disc 65 remains stationary although, the tariffdrum 75 receiving a backward movement in the direction indicated by thearrow F1, the pin 72 leaves the pin 71 on which the ring 73 with thespring 74 acts. When the pin 72 is into contact with the'raised part orprojection 1 of the lever 68 (Fig. 16). the latter oscillates (Fig. 10)and in this manner leaves between its end 68Il and the pawl 66 a passage68 (Fig. 10) for the long tooth of the pinion 41. The latter (Fig. 12).under the action of the spring 74 on the ring 73 and the block 71 in`tegral with the disc 65 which rotates. can then turn through a few teethand registers a unit of the extras by means of a drum 49. The samemovement is repeated at each registration, that is to say every timethat the Hag is brought from the position Payment to the position Extrasand backwards. If th(` drum 49 carries for instance the numerals 00.then v50, then 00, the chauffeur has been obliged fo work twenty fivetimes the flag from Payment to Extras in order that v55 the screen 32.

[a taf/rater: y Zeer/lifes The different integrating devices are4'mounted in frame comprising two horiions as 189 (Fig. 12). The wholemay be easily removed by unsci'ewing only the screws o. The numeraldevice for the total miles (Figs. 6 and 11) 1s driven by the pinion 153on the spindle 157 engaging by means of a train of pinions 175 with aclutch wheel 178 (Fig. 6), which, at each revolution, moves a pinion 179through the space of two teeth, transmitting by a spindle 180 and apinion 181 the movement to the front disc 182 of the numeral device,thus registering the total miles wandered over by the vehicle, the wheel153 being indeed keyed on the spindle 157 (Fig. 36).

The numeral device for the engaged miles (Fig. 6) is driven by thepinion 151 when the latter is in engagement with the clutch 152 of thepinion 153. The transmission is effected by a train of pinions 176,mounted loosely on a spindle 177 which train gearing with the first disc183 indicating the hectometers.

The device for registering the time Not recording or Payment is actuatedin the following manner (Figs. 12, 6 and 7). Pin- 1 ions 109 and 110,connected together by a pin g are loosely mounted on the hub of a pinion108. The pinion 109, the teeth of which are rounded on their flange orend, is of the same diameter as pinion 108, and pinion 110 gears with apinion 111 which is in engagement with the first disc 187 of the devicefor registering the time of payment, when 113 is engaged with 109 bylateral displacement of 113.

The device for registering the total fare l acts as follows (Figs. 13,14 and 15) the disc pin 199 integral with the four teeth 57 carriesblocks or side projections 59, each followed by a recess m, and engageswith a pinion with four teeth 197 connected by a inion 196 byv means ofa spring 198. The pm 199 engages in a recess of the pinion 197 and whenthe both pinions are unwedged relatively one to another through Ll5degrees, they form in ,l plan a pinion with eight teeth.

At each disengagement or rotation of the disc 57, one of the blocks 59,meeting a tooth of the pinion 197, drives tlie latter, that` permittingthe following tooth of the pinion 196 i to engage with the recess m. Themotion of the disc 57 continuing, the following tooth of the pnion 196runs against the flat'periphery of the disc 57 and the motion of thepinions 196-197 is stopped, the members 196-197' being rotated throughtwo teeth, that is a fourth of revolution. The pinion 196 drives; bymeans of a pinion p, the first disc 184 of the integrating device of thenumber of disengagements (Fig. 2).

Said device avoids any smuggling, the teeth of the pinion 196, rubbingon the disc 57, oppose indeed any motion of rotation of the members196-197 and consequently, of the pinion p.

At the time of the return to zero, the disc 57, driven by the pawl 52 incontact with a tooth of the star 51, rotates through a backwardrevolution. This motion would be impossible if one of the teeth (197afor instance) of the pinion 197 met by the block 59 would not disengagebefore it by compression of the spring 198 and would not be in line withthe tooth 196 of the pinion 196. As soon as' the block 59 is passedaway, the tooth 197l takes again its position under the action of thespring 198 in order to be again thrown back` as aforesaid described, bythe succeeding block 59 (Fig. 14).

A lamellar spring 200, fixed in 200 on the cross-bar 191 (Figs. 2 and12), acts on a square part c (Figs. 13 and 15) integral with the pinions196 and p and prevents the teeth of the pinion 196 from beingaccidentally introduced in the recesses m of the disc 57.

This device permits` on the one hand, the driving of the integratingdevice in a direction and` on the yother hand, the backwards return ofthe disc 57 without driving in the contrary direction the integratingdevice which remains held.

The device for actuating the Extras is controlled by a mechanism similarto the mechanism described for registering the fare. A dog or sideprojection (Fig. 16) and a corresponding recess m of the disc 65 act ona train of pinions similar to that of pinions 196-197 described above,the pinion p of this train 196-197 actuating the small first drum 185(Fig. 2).

The registering device of the number of engagements (trips) is actuated(Fig. 2) by a dog 78 (with a corresponding recess m) fixed on the tariffdrum 7 5 which controls a train similar to that of train 196-197.However, as the movement is only effected at the moment at which theflag 2 is displaced between the position Extras and the position Vacantand can only rotate in one direction (the lever 12 engaging with theteeth 11a of the ratchet 11), the elastic connections between the twopinions 196, 197 can be cancelled. The pinions p of this train 196-197meshes with the first drum 186 of the integrating device of the numberof engagements or trips.

General working and the screen 32 is dropped. The disc27 Vand 'thecylindrical whole comprising the drums to 49 and the sliding members35are disengaged, see Figs. 18 and 23. The pin 63 of thewheel 64 is inContact With .the Jin 58 of the dise 57. The cam76 of thetari drumbearing against the pin 103 of the lever 101 pushesthe spring 104against the member (Figs. 4, 12 andl 36). The lever 105, drawn bythespring 105 towards the bottom of the cam 77 disengages, by means ofthe pin 107 (Fig. 4), theratchet wheel 115 from the flexible `pavvl 117.The levers kk137 and 135, being kon the cams 9 and 10 in the positioncorresponding to Vacant (Figs. 4, 8 and 37), the lever 137 draws, bymeans of the crank shaft 138 and vtowards theside of the casing, the.lever 139 pivotally mounted at 140 on a member secured to the l'casingB0. The

\ pin 141 drives the sleeve 142 (Fig. 36) and disengages the pinion 151from the pin 152 of the pinion 153, the pinion 151, having alsodisengaged the ratchet wheel 126 vfrom the pawl 125 integral with thewheel 124 by the pressure on the sliding Awhole 150, 149, 148,

j 147,128, 127, 129. At this position, the clock- Work mechanism isstopped and, the car is ruiming, thetotal mileage integrating device,driven by the pinions 153, 175, is aloneregis- 'l tering.

In order to put the taximeter at Tariff 1, the flag should be firstlowered through 30 and then taken back to Vacant, in order to end the`return to zero and to enga-ge the pinions 41 with the teeth De of thedrums 45 to 49. The fla" should finally taken forto be paid and Ext-ras(Fig. 17).T But before the end of this movement, the mileages and timeregistering devices have Worked as follows: The lever 137, hinged on theshaft 136 and driven by the spring 142, slides along the inclinedplan ofthe cams 9 and 10 and comes into contact with the cam 11.

A Tariff 1 The pin 141has moved the sleeve 142 and pushed `the pinion151 against the members 152 which enter the teeth-of 151. The pawl 144bearing on the ratchet wheel 145, pushes, by meansofthe members 147-149, the sleeve l127 against the -pin 116 of theshaft 112 and engagessimultaneously theratehetwheel 126 with the pawl 125 of the Wheel`124.If the 4ear is running, the motion is transmitted from fthe flexible 172to the wheel 124 through kthe pinion 146 in-engagement-.with the pinion129 (Tariff 1). vThe mileage integrating ldevice for the time ofengagement is then actuated together with the total mileage integrat-,ing device by the rpinion l151 kintegral with Simultaneously theinclined edge of the cam 77 of 75, ushing the lever 105 to-k wards thecentre o` the apparatus, causes the ratchet wheel 115, through the fin r107, to

be engaged VWith the pawllll 'o 117,118, 124. The clockwork mechanism isthus allowed to attuate, by means of 923,108,113,

the Wheel 124, because the cam 76 of 75 hasv caused the lever 101l tofall, the .spring 104" of which lever is dravvnaway fromthe member 10()ofthe clockwork mechanism.

'Consequently according to the'runnino' or thestopping of the car, thepinion 124 drives the Wheel 64 on theshaft 1,v which Wheel is moved ethroughy `they angular yspace corre# spending to the time of engagementeither' for the distance of the ycourse or forthe duraoi' its spring135?. Through the pin- 134, the

lever 135 drives onthe sleeve 133 the ratchet Wheel v131 of which .comesin Contact Withthe pawl 130 of .127, 129. The displacement of thetyre-Wheel of the car is transmitted to the pinions 143 and 132. Thediameter kof the pinion 143 greater than that of the -pinf i ion 146 andconsequently the rotation of the pavvl 144 being greater :than tliauofthe ratchetgwheel 145, this pawl ksprings ony the teeth of 145 (Fig.36). e l

i e .Teef 3 y The vflag being at thisposition, the cam 10 allows the'lever 137 to be moved ,towards the outside (Fig. 5) driving the sleeve142-151 4). Wing to the member 152., the 4pinion 153 remains inengagement With the pinion 151. But the sleeve 127 remaining alwayspushed towards 124 bythesleeve 133 of the Tari 3, has not been `movedand has heldin their position the members 1500, 149, 148 and 147., 146,145. A quicker transmission of the rotation to the Wheel 124 isrensured'by means of the pinions 149-128. The pawl 130 slides on theteeth of the ratchet-,Wheel 131., The pawl 144 y(Tari 1) is completelydisengagedfrom thewheel 145. y f. Owing to the above arrangement, duringthe Workingat Tariff 2, the Tarils 1 and 2 are simultaneously inengagement and during. the Working'at Tariif, the Tariffs 2`and Saresimultaneously in engagementi`l Neither intermediate position takesplace during which neither tariff is in engagement. j e
